Abstract
A common cathode electrode structure for vertical LED pixel package, includes a package carrier, vertical LED chips, a conductive column, an insulating isolation support, and a common cathode metal thin film layer. The vertical LED chips are arranged above package carrier, the package carrier includes anodes and a common cathode penetrating therethrough to be external connection point. The anodes are respectively corresponded and electrically connected to P electrodes of the vertical LED chips, and the conductive column is electrically connected to common cathode and N electrodes of vertical LED chips. The common cathode metal thin-film layer is formed on vertical LED chips, conductive column and insulating isolation support to electrically conduct the conductive column and the N electrodes. The anodes and common cathode are in the same plane, which can meet the requirements for embodying SMT for small-spacing LED display module.
